How to fix this? The handle has a set screw but there doesn't seem to be the square spindle shaft that the set screw holds on to...
I'm a nanny, I'm at work, we were just about to go to the park when one of the kiddos handed me the doorknob. I've been on my belly in the foyer using my phone flashlight, no spindle shaft to be found, and I didn't hear it hit the floor, I was in the hall approaching the door when it came off.
